Description

The HD44780U dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor.

Since all the functions such as display RAM, character generator, and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver. A single HD44780U can display up to one 8-character line or two 8-character lines.

Features : 

1.  5 x 8 and 5 x 10 dot matrix possible

2.  Low power operation support : 2.7 to 5.5V

3.  Wide range of liquid crystal display driver power : 3.0 to 11V

4. Liquid crystal drive waveform : A (One line frequency AC waveform)

5. Correspond to high speed MPU bus interface
